I mean isn't the purpose to sweat so as long as your are sweating isn't a regular sauna okay. I was using an infrared one at the crazy doctor's office who used inproper chelation for $40 a pop but belong to a gym that has a dry sauna so have been going there instead. I am careful and put towels under me and drink tons of water. I've decided to try and go every other day for 30 minutes.
